Ransomware fileending .ifigzpt

Hi,
I have a problem with a ransomware, I cannot find anything at the www. For understanding, I am not a network administrator or IT personal. Maybe there is a simple solution for my problem. There is a overview at https://www.avast.com/ransomware-decryption-tools#xdata. My type is not list. :frowning: Maybe somebody can give me some tips. Thank you in advance.

Kind Regards,
Chris
